    Primary cilia are hair-like projections that protrude from most mammalian cells and mediate various extracellular signaling pathways. Pancreatic ductal adenocarcinoma (PDAC) cells are known to lose their primary cilia, but ...
  • Yagi, Noriyoshi; Kato, Takehide; Matsunaga, Sachihiro; Ehrhardt, David W.; Nakamura, Masayoshi; Hashimoto, Takashi (Nature Research, 2021-06-17)
    Microtubules are severed by katanin at distinct cellular locations to facilitate reorientation or amplification of dynamic microtubule arrays, but katanin targeting mechanisms are poorly understood. Here we show that a ...
  • Nakamura, Masayoshi; Hashimoto, Takashi (MDPI, 2020-12-11)
    The latent left–right asymmetry (chirality) of vascular plants is best witnessed as a helical elongation of cylindrical organs in climbing plants. Interestingly, helical handedness is usually fixed in given species, ...
  • Jujo, Takanobu (The Physical Society of Japan, 2020-12-10)
    The weak localization effect on a linear absorption spectrum is investigated for disordered s-wave superconductors. The vertex correction is incorporated into the response function in a way that is consistent with the weak ...

    The Proof of Stake (PoS) protocol is one of the consensus algorithms for blockchain, in which the integrity of a new block is validated according to voting by nodes called validators. However, due to validatororiented ...
  • Zhang, Yuanyu; Nakanishi, Ruka; Sasabe, Masahiro; Kasahara, Shoji (MDPI, 2021-07-26)
    Unauthorized resource access represents a typical security threat in the Internet of Things (IoT), while distributed ledger technologies (e.g., blockchain and IOTA) hold great promise to address this threat. Although ...
